Engineering industries profits, especially in high income nations like in Germany, Austria threatened with 2x world natural gas prices.
PV, Wind, Hydroelectric as based electricity supply (up to 40% in 2020?)
Reducing need for polluting Coal, and expensive, foreign controlled (mainly Australian, Russian and South Africa) nuclear power electric generation.

Biogas to burned when electricity production is low in PV, Hydroelectric and Wind.
While energy is stored by reverse pumping in Water Reservoirs, (ha ha cheap batteries)

Believe Germany and Japan will be world leaders in that field.

The Russian Federation has positioned itself, and are willing to go to WAR to be "Protector of the Energy Supplier Guild".

The British Club used to have that honour, so, I would think the likely attempt by the British would be to form an GRAND ALLIANCE (allianz grande) with France, Trade Route states (especially Korea, Taiwan). Korea won't be very friendly to Russia, or USA because they realized that their state will be USED to start a conflict to bring chaos to Japan and China.

Suggest British-France develop 5TH GENERATION air superiority fighters.
While Taiwan, Korea build BATTLE TANKS, DOCKSHIPs, and SUPPORT FIGHTER BOMBER aircrafts.
At least it could compete with the Russian Federation for the ENERGY BLOC influence.

Mr. Obama just "talking frank", on how long the world would finance it's debt especially now a large nation (CHINA) is not a nation to be compelled by their ARMED FORCES like Japan, Korea, Taiwan, Singapore is at the moment.

CHINA IS NOW!
It has changed the world political equation and created a NEW ORDER!

Boy! Never know, Germany could make RENEWABLE...

....cheap and efficient? Or it has industries that can pay for this range of expensive products.

Strange as it may be seen, it's a watcher!!!!
Doing it at 10% is reasonable, but talks of 40% to 50% renewable by 2020 is absolutely interesting.
but Germany has the EURO, it can create a lot of jobs to it's engineering industries, while importing commodity goods from overseas!
so, it's not so crazy after all for Germans.

I read again the Beijing China Daily -chicken farm biogas project.

And boy!

if 60,000 tonnes of corn based feedmill can feed 3.0 million chicken egg farm for a year.
(approximately 1kg = 2.5kg of feedmill for normal broiler chicken, i think)

so, it can produced approximately 5,000 liquid methane to produce about US$1.45 million worth of electricity.
(just a simple approximation, didn't dare to pick up data randomly from the internet (without some analysis), pretty misleading data obtained)

so, if China has 1,300 million people eating around 350kg of grain, meat, vegetable
and the equivalent 200kg of grain for the animals raised for meat.
it could mean as much as 650 mT of probable hydrolysed bio-gas materials.

We could produce 50 MT of liquidified methane by just emphasizing enviromentalism.
It's there anyway and we don't want to rubbish our cities and rural village! correct?
A more sanitized city and village enviroment must be good for the people!

ha ha ha

Of course, we should do it when the country can afford the enviromentalism.
(Malaya should be implementing such too, maybe by encouraging clustering of chicken, pork farms too!)
